Heron Explorer

The Heron Explorer is a CLI tool that you can use to gain insight into a Heron installation, including:

which clusters are currently running in the installation

information about a given topology’s components (spouts and bolts)

metrics for a topology

the containers in which a topology is running

the topologies running in a given cluster, role, or environment

The Heron Explorer vs. Heron CLI

There are two important differences between the Heron Explorer and Heron CLI. Unlike Heron CLI, the Heron Explorer (a) requires the Heron Tracker and (b) performs read-only, observation-oriented commands (rather than commands for actions like submitting, activating, and killing topologies).
